对某锅炉前后管板裂纹及爆管的事故分析与处理

Accident Analysis and Processing of Front and Back Tube Plate Cracking and Tube Explosion of a Boiler

为了确保锅炉水处理检验工作质量,防止和减少由于结垢、腐蚀及蒸汽质量恶化而造成的事故,促进锅炉运行的安全、经济、节能、环保,本文对吉林某航空院校锅炉,在使用运行过程中没有建立建全水处理管理、岗位职责、运行操作、维护保养等制度及化验员检验指标不真实的状况进行分析。经笔者监督检测了锅炉给水的硬度YD=6.5mmol/L,溶解固形物5000mg/L,锅水碱度、悬浮物严重超标,及其它指标均不符合标准。该校锅炉化验员没有认真执行GB/T1576-2008《工业锅炉水质》标准要求,造成锅炉严重结垢、腐蚀爆管等事故,经分析,提出解决及处理方案。

In order to ensure the quality of water treatment of boiler inspection, prevent and reduce the accident due to fouling, corrosion and steam quality deterioration, and promote safety, economy, energy saving, environmental protection of boiler operation, this paper analyzes the situation of without building the complete water treatment management, job responsibilities, operation, and maintenance system and unreal lab technician test index in the operation process of the boiler in a Jilin aviation college. The supervision and inspection of the boiler feed water hardness, YD=6.5mmol/L, dissolved solids 5000mg/L, suspended boiler water alkalinity seriously exceeds the standard, and other indicators do not meet the standard. The school boiler technicians do not seriously implement the requirements of standard GB/T1576-2008＂quality＂of industrial boiler, which causes the accidents of serious scaling and corrosion of boiler tube explosion. After analysis, this paper proposes the solutions and the treatment schemes.
